Abstract

The gear rim (3) that drives it is housed on the rotating drum (1), helical teeth (12) is arranged on the gear rim, by one flexible, the housing of truncated cone (5) adapts to the distortion of drum and absorbs because the axial pressure that causes during helical teeth work.Gear rim counter-bending in one side by the rigidity of housing (5), at another side then by the effect of stiffening ring (9).

Description

Rotating drum assembly
This is an invention about rotating drum transmission device, and for example rotary kiln or tube-rolling machine are equipped with gear rim on drum, and gear rim radially is being separated with drum, and the outer ring of drum utilizes flexible connecting mode connecting gear rim.
Gear rim is installed on the rotating drum by flexible connecting mode, and the out of roundness of drum is compensated, and avoids making drum produce distortion such as the cause of heat, and causes increase load on gear rim, and these all are well-known.
Can recognize that from U.S. Patent application US-A-2999396 pass through in sheet spring and the joining mode of rotary kiln at gear rim, an end of sheet spring is fixed on the gear rim, the other end then is fixed on the drum.
From Fig. 1 of German patent application DE-A-2604425, can know in flexible connection the between the cylindrical of tube-rolling machine and the gear rim and comprise a tubular member concentric with tube-rolling machine, this tubular member is radially being separated with the cylindrical and the gear rim of tube-rolling machine, and an end and tube-rolling machine, the other end and gear rim flexibly link, the purpose of this flexible connection also is in order to compensate the out of roundness of tube rolling body, and avoids increasing load owing to thermal distortion causes on gear rim with this.
But, also do not have a kind of flexible connecting mode to be suitable for giving drum now with the axial force transmission in the helical gear rotation.Helical gear in rotation compared with spur gear have one superior aspect, that is exactly when the identical moment of torsion of transmission, might do gear rim to such an extent that be rather narrow.But the axial load on this gear rim that acts on known gear can make gear rim produce.Its result causes gear rim to contact with line between its meshed gears to become a contact, therefore increased the wearing and tearing of gear part greatly.
Purpose of the present invention is exactly the unfavorable aspect that will overcome in the above-mentioned known gear.According to the present invention, drum assembly comprises that a rotary drum and one radially are being separated with drum, and with the joining gear rim of flexible connecting mode and drum outer ring, the tooth that it is characterized in that gear rim is a helical teeth; Flexible coupling part is the housing of a truncated cone, the end that housing is narrow, and the diameter of its diameter and drum cylindrical is suitable, and is fixed on the outer ring of drum.The end that housing is roomy, the diameter of its diameter and gear rim is suitable, and is fixed on the side of gear rim.Housing extends to its direction of gear rim just in time on the direction that housing is under pressure from its connection place, this pressure is to be produced during with the gear engagement work that is meshed by the helical teeth on the gear rim.At the opposite side of gear rim, a stiffening ring is arranged, have identical rigidity diametrically with housing on the relative side, be separated with drum simultaneously.
Compare with other known flexible connection, the housing of truncated cone is formed a very simple and firm structure, out of roundness to drum is recompensed, the thermal distortion of drum also can not produce significantly load to gear rim, and can be the very big axial force transmission that is produced during helical teeth work on the gear rim to drum.
Stiffening ring is guaranteed the shaft axis of gear rim under the acting in conjunction of radial force and axial force, all the time with the shaft axis keeping parallelism of drum, so that the tooth on the gear rim contacts with the tooth retention wire of actuation gear.
Gear rim can be connected respectively with the mode of welding with truncated cone housing and stiffening ring, but it is more convenient truncated cone housing and stiffening ring being fixed by bolts on the surface of same support on two sides of gear rim respectively, and therefore gear rim can change the direction utilization.When wearing and tearing occur in side of tooth, the bi-side of gear rim can be changed easily, and directly truncated cone housing and stiffening ring be fixed.
Below by the mode of giving an example, with reference to accompanying drawing the present invention is done one and discuss in detail.Accompanying drawing is the axial, cross-sectional view by drum assembly.
As shown in the figure, drum 1, for example a rotary kiln or a tube-rolling machine are driven around axle 2 rotations by the gear rim 3 with helical teeth 12, and the mode of driving is known, and axial force that acts on the gear rim when driving is as arrow 4 indications.Gear rim 3 is to be driven with the known kind of drive by a gear that is not illustrated.
Gear rim 3 by one around drum, truncated cone housing 5 is connected on the drum 1, the diameter of leptoprosopy one end of truncated cone housing is suitable with the diameter of drum cylindrical, both is fixed up by the flange on flange on the housing 6 and the drum 7 with bolt.
Wide one end of housing 5, near and be fixed on the side of gear rim 3, facing because helical gear effect produces, as arrow 4 indications, the force direction that gear rim bears.On this end of housing 5, as shown in the figure, a flange 8 is arranged, use bolt with gear rim 3.
On the opposite side of gear rim, with bolt a stiffening ring 9.
Form the seam plane 10 and 11 that falls in respectively on the bi-side of gear rim, arranged thereon the flange 8 of truncated cone housing and the screw of stiffening ring 9 are installed, the seam of bi-side is consistent.Therefore, through after certain wearing and tearing, the housing and the stiffening ring that are contained on the gear rim can be removed at the tooth of gear rim, two sides of the gear rim of turning round, and then flange 8 and stiffening ring 9 be fixed by bolts on the gear rim.
Truncated cone housing 5 has constituted a flexible connection radially between gear rim 3 and drum 1, avoid because the thermal distortion of the out of roundness of drum and drum increases load for gear rim 3.
The effect of stiffening ring 9 is under the situation of can not the full remuneration possible distortion of housing 5, guarantees that the axis of gear rim 3 parallels with the axis of drum.Thereby the tooth that has guaranteed tooth on the gear rim and actuation gear keeps desirable line to contact when engagement.

Claims (2)

1, a kind of drum assembly comprises a rotatable drum (1) and a gear rim (3), gear rim is the outer ring that is installed in drum by a flexible coupling (5), and gear rim and drum are radially separated from each other, it is characterized in that gear rim (3) has helical teeth (12), flexible connection is the housing (5) of a truncated cone, the diameter of one end of its leptoprosopy is suitable with the diameter of drum cylindrical, and be fixed on the cylindrical of drum, the diameter of the end that housing (5) is wide is suitable with the diameter of gear rim, and is fixed on the side of gear rim; Housing extends to gear rim from the connection place of drum, gear rim by transmission in, be in because the effect of helical teeth produces on the direction of pressure to housing; On another side of gear rim, a stiffening ring (9) is arranged, also be separated with drum, the same with the truncated cone housing radially have identical rigidity.
